ROAD MARKING MACHINE Filed April 19, 1957 5 Sheets-Sheet 3 ATTORNEYS Patented May 3, 1938 UNET ST 3 Claims.

This invention relates to street or road marking machines especially adapted for quickly, accurately and evenly applying paint on roads or streets in stripe formation, and has for the pri- 5 mary object the provision of a portable device of this character which may be propelled with minimum effort and guided accurately along a predetermined path and which will assure an even distribution of paint on the surface of the street or road and may be easily rendered operative or inoperative.

With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure l is a side elevation, partly in section, illustrating a road or street marking machine constructed in accordance with my invention.

Figure l2 is a top plan View illustrating another modified form of brush.

Referring in detail to the drawings, the numeral l indicates a frame on which are secured axles 2 having journaled thereon ground wheels 3 preferably three in number so that the device may be more conveniently steered from the rear thereof. A paint reservoir i is mounted on the frame and is provided with a removable cover held in position by a securing device 6 consisting of a feed stem l engageable with the cover at one end and provided with a hand wheel 8 at its other end and threaded in a bearing 9 forming integral parts of jaws l0. The jaws (Gl. Sil-Mil?) lil are engageable'with lugs il formed in the reservoir. rIlhe reservoir i when closed by the cover 5 is sealed .against the escape of air and air pressure may be introduced in the reservoir t by an air tting l2 equipped with a pressure Vgauge i3. An outlet pipe lil is connected with the bottom of the reservoir and extends downwardly and rearwardly and is equipped with a4 control valve l5, the purpose of which is to regulate the flow of paint under pressure into the reservoir and permit the flow of paint to be stopped whenever desired. Arranged on the frame l and adjacent the reservoir Il is a tool box l5 having a removable cover il. A pointer i8 is adjustably secured to the forward end of the frame and is an aid to a person guiding the device along a predetermined marking or path.

A handle construction I9 consisting of a handle bar 2d supported by side bars 2i is employed by a person when propelling and guiding the device. The side bars aresecured to the sides of the frame i and extend upwardly and rearwardly therefrom and the handle bar 2li includes sections 2l and 22. The section 22 is fixed on one of the side bars while the section 2i is journaled on the other side bar and may be locked against rotation by a removable pin 23. A link Z4 is pivoted on the operating arm of the valve l5 and to a bracket 25 on the section 2l of the handle bar whereby the operator from a propelling position may open and close the valve as desired.

Journaled on the rear axle of the device are arms 26 and secured to the rear ends of said arms are vertically arranged attaching members 2l carrying at their lower ends pintles 28 and also secured to the attaching members are braces 2Q which extend forwardly and downwardly and carry pins 3d engageable with a head 3| of a brush 32. The pintle pins of the pintles 28 t in bearing openings in the head 3l and of a size to permit the head to have a side tilting movement in either direction. The journal ends of the arms 26 have connected thereto coil springs 33 which are in turn adjustably connected to an lequalizing bar Sli pivoted on the frame l, as shown at 35. The springs 33 act to urge the brush carrying ends of the arms downwardly to bring the brush in contact with the surface of the road or street and due to the way in which the brush is journaled on the attaching members 2l either side of the brush may tilt upwardly when engaging an obstruction and when passing thereover will be immediately brought to contact the surface of the road or street evenly by the springs 33. Links 35 are pivoted on the upper ends of the attaching members 2l and on the axle and parallel the arms 26. Flexible elements 3l are secured on the links and to arms 38. The arms 38 are secured on a shaft 39 journaled on the frame I. Connected to the shaft 39 is a connecting rod 40 which is in turn pivoted on an arm 4l carried by a sleeve 42 journaled and slidably mounted on the section 22 of the handle bar 20. A hand grip 43 is secured on the sleeve 42 to permit the operator to rotate said sleeve for a limited distance in either direction and also to slide the sleeve against the action of ay spring 44. The spring 44 normally acts to urge a lug 45 on one end of said sleeve against a collar 46 provided with a notch 41. The lug 45 when it enters the notch 41 secures the sleeve 42 against rotation and in a position to support the brush elevated from the ground or in an inoperative position, as shown in Figure 3. As soon as the lug 45 is disengaged from the notch 4T the springs 33 act to move the brush into engagement with the ground.

Referring to my modified form of mounting of the brush on the axle, as shown in Figure 5, arms 48 are journaled on the rear axle and have connected to their forward ends springs 33 and carry at their rear ends pinties to engage in the journal openings of the brush head. Plates 43 are adjustabiy mounted on the arms 48 and carry pins 50 to engage with the brush head. The iiexible elements 3l are connected to the arms 48 rearwardly of the journal of said arms. The brush mounting shown in Figure 5, operates similar to the brush mounting described in connection with Figures 1 to 3 of the drawings.

The head 3| of the brush 32 includes spaced longitudinally extending members l to which tufts of bristles are secured. The tufts of bristles are' arranged on each member 5| in a longitudinal row and have applied thereto a guard 52-acting as a reinforcement for the tufts of bristles. A transverse member 53 is pivoted on the members 5l and carries a row of tufts of bristles 54. The tufts of bristles carried by the member 53 are arranged at right angles to the tufts of bristles carried by the member 5 I Therefore, the rows of tufts of bristles described form therebetween a space in which is discharged the paint from the reservoir 4 so that said paint when engaged by the bristles will be smoothed into stripe formation. The angle of inclination of the member 53 may be varied byan adjusting means 55. The members 5l are connected together by a brace 56 which supports the adjusting means 55. The brace 55 is located well above the surface of the ground when the bristles are in engagement therewith so as not to interfere with the paint.

Referring to my modified form of invention the transverse row of bristles are located intermediate the ends of the members 5l and the paint is discharged both forwardly and rearwardly of the transversely arranged bristles, as indicated by the dotted line in Figure l0. In this instance, the control valve has connected thereto spaced nozzles 57, as shown in Figure 11. The form of brush, as shown in Figures and 11 besides having the transversely arranged bristles intermediate the ends of the side members 5I also has a transverse row of bristles, indicated by the character 58, which trails the other row of bristles and which are indicated by the character 59. Instead of forming the brush head of substantially U-shape, as shown in Figure 6, it may be constructed of triangular shape, as indicated by the character B0, and the rows of bristles extend along all sides of the triangle, as indicated by the character 6i The triangular shaped head has the apex thereof disposed in the direction of the forward end of the machine.
